Perbedaan Kecepatan Kematian Larva Aedes aegypti Strain Surabaya dengan Pemberian Abate 1 SG

Abstract

Dengue Hemorrhagic Fever (DHF), or abbreviated in Indonesian to “DBD”) is an infectious disease which is caused by dengue virus. This type of disease is one of the major health problems in Indonesia that results in illness and death. Indonesia is ranked second after Thailand that has a high rate of an Extraordinary Outbreak (“KLB”) of DHF. The main DHF vector in Indonesia is Ae.aegypti. One of the possible alternatives to curb the population of its larvae is by means of a chemical control mechanism called abate. One of the abate products that is widely used in Indonesia is the Abate formula of Sand Granules (SG). WHO has recommended that the abate be safe to use and does not create side effects (intoxication) on human and pets. The test of the extend of abate 1 SG with a dose of 0.025 gr in 250 ml of water with a number of larvae instars of Ae.aegypti was conducted by strewing abate on a bowl containing larvae with an absence of food or predator. This study is classified as an experimental laboratorial research. Direct observations were performed by identifying the number of dead larvae in accordance with the course of time (hour) up to the death of all larvae. The results of the experiment show that regarding the death speed of Ae.aegypti larvae instars which is based on the course of time (hour) there is a difference with a maximum period of seven hours. Larvae instars I died the earliest (the 4th hour), larval instars II and III died at the 6th hour, and larva instars IV died the last (the 7th hour). The result of the statistical test of Kruskall Wallis indicates a significance value p=0.0001 or p<0,01,and then continued with test of Kolmogorov Smirnov indicates a significance value p=0.002 or p<0,01. The figures have fulfilled the objective and hypothesis of the research, and drawn a conclusion that there is difference in the death speed of Ae.aegypti larvae instars I, II, II and IV with the extend of abate 1 SG.
